All of my basement windows have something near them like a water tank or pvc pipe. Otherwise I would do the same thing. Probably wouldn't use the tread mill tho. But use what you got right?
In their defense... it was startin' to spit snow... so the ole treadmill, that never gets used... seemed like a gooder ideer to speed things up...
a much better use, according to what I read, he can fill from front to back by changing the speed. Of course now he needs a super split to up production!
